Have a servlet and it can run inside TomCat. However, I am not sure how to debug it inside Eclipse(Java Standard version). Any suggestions?

A Java program can be debugged simply by right clicking on the Java editor class file from Package explorer. Select Debug As → Java Application or use the shortcut Alt + Shift + D, J instead.
Set a BreakpointWorkshop extends the Eclipse debugger to allow you to debug JSP code. To set a breakpoint: Right-click in the gutter of the Source view and select Toggle Breakpoints.
You need to download the eclipse ide for JavaEE developers. Creating servlet example in eclipse ide, saves a lot of work to be done. It is easy and simple to create a servlet example.
Add the server runtime to the web project to fix the HttpServlet not found Eclipse error. This will add all the JAR and ZIP files used by the servlet engine to the web project's runtime path. When this step is complete, rebuild the project and the HttpServlet not found Eclipse error message will go away.
First ensure that you're using "Eclipse IDE for Enterprise Java Developers", with the Enterprise in its name, and thus very definitely not just "Eclipse IDE for Java Developers".
Once ensured/upgraded, put breakpoints in the servlet code the usual way and run the server in debug modus. Rightclick the server in Eclipse and choose Debug instead of Start (or click the bug button instead of the green arrow on the button panel of the servers view). Then fire a HTTP request on the servlet using your favourite webbrowser. Eclipse will open and focus the debug panel when the particular code line with the breakpoint is about to be executed.

Right-click on project -> Debug as -> Debug on server should do the trick
